Hello! I recently created a project using restaurant data from OpenStreetMap. I was curious how the data compares to Overture Places restaurant data, so I did some analysis myself of it. Thought I’d share here!

Thanks for carrying out this assessment and writing up your findings. We need more extrinsic analyses along these lines to gauge completeness parity. Some suggestions for further steps:
- Refine your OSM confidence metric by ignoring edits by bots such as woodpeck_fixbot and b-jazz-bot (which doesn’t distinguish domain squatters as it touches
websitetags) - Repurpose the heuristics from intrinsic quality analyses as confidence factors
- Sample enough POIs to compare parity levels across geographies or population densities
- Compare OSM and Overture coverage of a wider variety of POI types, especially those that Google Maps may not cover as well
- Use another third-party data source as a baseline, such as AllThePlaces, Yelp, or Foursquare
